Does the car refrigerator need to go through the electricity?
Car refrigerator is the use of semiconductor refrigeration components, so its cooling function is relatively small. If you need to use it for a long time, you have to power up. If you can not power. Car refrigerator is energized on the cooling, but the cooling effect is slower.
There are two kinds of car refrigerator on the market, one is the semiconductor car refrigerator, its principle is to rely on electronic chip cooling, the use of special semiconductor materials constitute the PN junction, the formation of thermocouple pairs, resulting in Peltier effect, that is, by DC cooling A new type of refrigeration method. The cooling temperature range is 5 to 65 degrees. The advantages of this refrigerator is both cooling and heating, environmental protection, pollution-free, small size, low cost, work without vibration, noise, long life. The disadvantage is that the cooling efficiency is not high, the cooling temperature is affected by the ambient temperature, the cooling can not reach below zero, and the capacity is small. The other is the compressor refrigerator, the compressor is the traditional traditional refrigerator technology, cooling temperature is low, -18 degrees 10 degrees. Cooling efficiency, can ice, fresh, large size, is the future direction of the development of car refrigerator. But this weight is heavy, easy to carry, the price is higher. Compressor Car refrigerator compressor The world's leading producer for Germany and Japan.
